If a mining can't be paused due to technical issues how would you stop the mining operation? Would you need to physically remove the workers? un-power? Suggestions, theories, actual things that have worked for you?
Would prefer not having to visit each mine physically, but I can't think of any other way..

You mentioned firing the workers Ellias, and I see there is an action for that, what would that do? I'll have to look into that, if it wouldn't cause alot of problems that may be a solution.

According to the bug report I filed, it, (pause) feature is corrected, but the fix will not be implemented until a system sync. And it's already been several mining cycles, I am trying to think of a way to stop mining before overloading and shutting the mines down and having to physically return to each and resetting them; but all the things I can think of, besides the pause feature, as you mentioned involve a physical termination of the operations.
Hoping maybe someone had found a workaround.

Thanks Ichiru and Photino,
I know in the past if I kept, pausing the mine it would eventually pause, however this time I'm not having any such luck.
I probably could have an ASIM pause them for me, and may have to resort to request that, but I hate to bother anyone if a sync is close. I realize they have quite a bit on their plates at the moment.
Thank you both very much, though..

I was hoping a sync would occur, but I understand that may not happen for a while.
Rather than fire the npc's and being unsure of the consequences, and the possibility of losing a group of haulers, I've submitted a support ticket, as suggested. It seemed the least likely to create any unforeseen results. If I could be sure that I wouldn't overflow the mines, I would have continued to wait out the new sync. I appoligize for any inconvenience this may cause, and appreciate the help.
